----------- [ Current event for CA_DiabloCanyon_2 @ 100 % RX Mode: Power Op ]

20180424 | CA_DiabloCanyon_2 | CONTAINMENT RADIATION MONITORS INOPERABLE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53361

"At 0357 [PDT], Unit 2 Containment High Range Radiation Monitor RM-31 was declared inoperable due to erratic indication. At this time, Containment High Range Radiation Monitor RM-30 was out of service for routine calibration.

"With both containment high range radiation monitors inoperable, this impacted DCPP's [Diablo Canyon Power Plant's] ability to evaluate containment radiation data for an unmonitored release in the event of an emergency. Compensatory measures were promptly put in place with the use of a portable radiation monitor as required by emergency preparedness procedures.

"This condition is being reported as a loss of assessment capability in accordance with 10 CFR 50.72(b)(3)(xiii).

"Actions are in progress to restore RM-30 and RM-31 to operable status.

"The NRC Senior Resident Inspector has been notified."

* * * UPDATE ON 4/24/18 AT 1716 EDT FROM ERIC THOMAS TO DONG PARK * * *

RM-30 was restored to service. Portable radiation monitoring is not required.

The licensee will notify the NRC Resident Inspector. Notified R4DO (Vasquez).
